WebResearch on Utilization Rate of Cesium Atoms in Optically Pumped Cesium Beam Tube Abstract: The main factors that affect the life of the cesium beam tube include the … WebA more symmetric beam reversal is possible with optical pumping methods, since all atoms may be included regardless of velocity and position within the beam. This should permit a better cancellation of cavity phase shifts. Angle tuning of the laser may result in velocity selection of atoms in the cesium beam, favoring slower velocity atoms, which
WebLaser-pumped cesium beam atomic clocks have been under development over the last 20 years. Optical pumping allows for the utilization of essentially 100% of the atoms in the beam, " improv- ing the clock signal-to-noise ratio over that of similar beam clocks using magnetic state selection by factors between 5 and 10.
WebJun 7, 2024 · Optically pumped cesium beam atomic clocks use two hyperfine levels of cesium atoms ( F = 3, m F = 0> and F = 4, m F = 0>. In order to separate the other magneton levels from the two levels, we add a weak magnetic field, called C field.
